/*******************************************************************
|
|
*
|
|
* Error Exit
|
|
*
|
|
* You can call the library routines that handle run-time errors
|
|
* from your own program. One of these, called strerror, will
|
|
* print a text run-time error message to standard output. You
|
|
* pass a single integer parameter, which is the run-time error
|
|
* number. This procedure is generally called from an error trap
|
|
* subroutine - see the sample program ERRORTRAP.CC for an example
|
|
* of how to trap errors. In this program strerror is used to
|
|
* list the current run-time error messages.
|
|
*
|
|
* The two built-in macros __FILE__ and __LINE__ are used to print
|
|
* the current line number and the name of the current source file.
|
|
*
|
|
* The library subroutine SystemErrorLocation provides trace-back
|
|
* information; it is further covered in the text sample program
|
|
* ERRORTRAP.CC.
